If your partner, in the past, was not very protective of their phone and “if you notice a change in phone habits — like suddenly on silent all the time”, it could be a sign that there’s something on there that they don’t want you to see, says author Marina Sbrochi.
You’ve probably had no issue using your partner’s phone for something in the past – but now, they seem to be extremely protective, even going so far as to put a lock on it that prevents you from opening it.
2. THEY’RE (TOO OFTEN) HOME LATE FROM WORK
If your partner is usually home by a certain time every day, but suddenly they’re staying late at work, it could be an excuse for them to see someone else behind your back. It’s a common enough excuse that many people don’t think too much about.
As dating and relationship advice and etiquette expert April Masini says, “When someone stops coming home at the regular time, on a regular basis, be wary. When a schedule changes and there’s no comment about why or what he or she is doing differently, it may be because your spouse is cheating on you.”
